Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The low-power management of the embedded system aims to reduce the energy consumption of the system as much as possible to prolong the standby time of equipment on the premise of meeting the performance requirements of users, and the contradiction between high performance and limited electric quantity is most prominent in the embedded system, so that the combined application of the hardware low-power design and the software low-power management becomes an effective means for solving the contradiction. The current low-power management mainly comprises three implementation modes, wherein the first implementation mode is a processor power management mode, namely, dynamic management of the frequency of a central processing unit and adjustment of a working mode when a system is idle so as to reduce power consumption; the second implementation is device power management, mainly by turning off individual idle components to reduce power consumption; a third implementation is system platform power management, which is mainly specifically tailored to the unusual devices of a particular system platform. The iridium device in the iridium system adopts the third implementation mode to reduce power consumption.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, and as shown in fig. 1, includes a terminal device 11, an iridium device 12, and an iridium 13.
The terminal device 11 may be, for example, a mobile phone or other device, the connection between the terminal device 11 and the iridium device 12 may be established through bluetooth, and the iridium device 12 may be a handheld device. The iridium 13 is a satellite, and data transmission can be performed between the terminal device 11 and the iridium 13 through the iridium device 12, that is, the iridium device 12 can be used as a relay device between the terminal device 11 and the iridium 13.
The iridium device 12 may adopt a system-level power management scheme, and two different operation modes, namely a standard mode and a low power consumption mode, are set for the communication needs of the iridium device 12. The low power consumption mode is relative to the standard mode, a Micro Controller Unit (MCU) in the iridium device 12 in the low power consumption mode goes to sleep, and a transceiver module and a GPS module of the iridium device 12 are powered off, so that the power consumption of the iridium device 12 is reduced to the maximum.
The low power consumption mode is a main technical means for reducing power consumption of the iridium device 12, in the low power consumption mode, since an operating system of the iridium device 12 stops working, communication between the terminal device 11 and the iridium 13 cannot be performed, and when communication between the terminal device 11 and the iridium 13 is required, the operation mode of the iridium device 12 needs to be switched to the standard mode.
An application scenario of the present application is described in fig. 1, and a detailed description of the solution of the present application will be provided below with reference to fig. 2.
Fig. 2 is a schematic flowchart of an iridium satellite device control method provided in an embodiment of the present application, where the method is applied to an iridium satellite device, and as shown in fig. 2, the method may include:
and S21, switching the operation mode of the iridium device from the low power consumption mode to the standard mode according to the interrupt event of the iridium device in the low power consumption mode, and establishing a session with the iridium device in the standard mode, wherein the iridium device establishes Bluetooth connection with the terminal device.
The operating mode of the iridium device comprises a standard mode and a low power consumption mode, wherein in the standard mode, the iridium device detects good iridium signals, and can be used as a relay between the terminal device and the iridium to realize data transmission between the terminal device and the iridium; in the low power consumption mode, the iridium device enters a sleep mode, the transceiver module and the GPS module of the iridium device are powered off, the MCU in the iridium device can also carry out the sleep mode, and the MCU is turned off, so that the standby power consumption of the iridium device is reduced.
The iridium device is connected with the terminal device through Bluetooth, and the distance between the iridium device and the terminal device needs to be within a certain distance range so as to ensure better Bluetooth connection quality between the iridium device and the terminal device.
After the iridium device is powered on and initialized, the iridium device enters a low power consumption mode by default so as to ensure that the standby power consumption of the iridium device is reduced and prolong the standby time of the iridium device. When the iridium device is in the low power consumption mode and an interrupt event occurs, the iridium device is awakened, and then the iridium device switches the operation mode from the low power consumption mode to the standard mode according to the interrupt event.
In the process of switching from the low power consumption mode to the standard mode, each part in the iridium device, which enters the sleep state, is also awakened to enter a normal working mode, and then the iridium device determines whether to establish a session with the iridium device according to needs. The interruption event of the iridium device in the low power consumption mode can be triggered internally or externally by the iridium device.
And S22, carrying out data transmission between the terminal equipment and the iridium satellite.
When the iridium device is switched from the low power consumption mode to the standard mode and detects that the iridium signal is good, the iridium device can be used as a relay between the terminal device and the iridium to transmit data between the terminal device and the iridium. The data transmission may include uplink data transmission, that is, the terminal device sends data to the iridium satellite through the iridium satellite device; the data transmission may also include downlink data transmission, that is, the iridium satellite sends data to the terminal device through the iridium satellite device.
According to the iridium device control method provided by the embodiment of the application, the operation mode of the iridium device is switched from the low power consumption mode to the standard mode according to the interrupt event in the low power consumption mode, whether a session is established with the iridium device is determined according to the service requirement in the standard mode, and the bluetooth connection is also established between the iridium device and the terminal device, so that when the iridium device detects that the iridium signal is good, the iridium device can be used as a relay to perform data transmission between the terminal device and the iridium device, and uplink data transmission and downlink data transmission can be included. According to the scheme of the embodiment of the application, when data transmission is not needed, the iridium device is in a low power consumption mode of timed awakening so as to reduce standby power consumption, and the iridium device can be timed awakened to update self state information and detect whether uplink data and downlink data exist or not under the low power consumption mode of timed awakening so as to perform corresponding processing; when data transmission is needed, the operation modes are switched according to the interrupt event, data transmission between the terminal equipment and the iridium satellite is completed after the operation modes are switched, reasonable switching of the operation modes of the iridium satellite equipment can be achieved, and normal communication between the terminal equipment and the iridium satellite is guaranteed under the condition that standby power consumption of the iridium satellite equipment is low.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 3 is a schematic structural diagram of an iridium satellite device provided in this embodiment of the present application, and as shown in fig. 3, the iridium satellite device is composed of a main control chip, a positioning module (including a positioning antenna and a GPS), a communication module (including an iridium satellite module and an iridium satellite antenna), a bluetooth module, a Power supply module, a Power-on key, an LED indicator, a battery, and a flash memory, where the battery may be, for example, a lithium battery, the main control chip is a chip supporting a Low Power Universal Asynchronous Receiver/Transmitter (lpart), the bluetooth module is responsible for data communication between the iridium satellite device and a terminal device, and 4 LED lamps are used for indicating signals, electric quantities, and other states.
The iridium device further comprises an interrupt module, the interrupt module can trigger interrupt according to an interrupt event of the iridium device in the low power consumption mode, and then the main control chip switches the operation mode from the low power consumption mode to the standard mode according to the interrupt triggered by the interrupt module.
Fig. 4 is a schematic diagram of triggering an interrupt according to an embodiment of the present application, and as shown in fig. 4, the interrupt module may include a timer, an LPUART module, and an Input/Output (IO) module, where different modules trigger different interrupts.
The timer can start timing after the iridium device enters the low power consumption mode, and the duration of the timer can be preset. When the running time of the timer reaches the preset time, the timer triggers the timer to be interrupted, the main control chip switches the running mode from the low power consumption mode to the standard mode, and then the state information of the iridium device is updated. When uplink data to be transmitted are in a transmission cache of the iridium device, the iridium device establishes a session with the iridium device and transmits the uplink data to the iridium device. When the sending cache of the iridium device does not have the uplink data to be sent, the iridium device still establishes a session with the iridium device, and judges whether the iridium device has downlink data to be sent according to the response information sent by the iridium device. And if the iridium satellite has downlink data to be issued, the iridium satellite equipment receives the downlink data sent by the iridium satellite after establishing a session with the iridium satellite, and sends the downlink data in the receiving cache to the terminal equipment after the iridium satellite equipment receives and stores all the downlink data sent by the iridium satellite into the receiving cache.
The interrupt triggered by the LPUART module is an interrupt triggered according to the indication of the terminal equipment. When the terminal equipment has the requirement of uplink data transmission, the terminal equipment can send uplink data to be transmitted to the iridium device through the Bluetooth, and the LPUART module triggers the receiving interruption in response to the reception of the uplink data to be transmitted from the terminal equipment. And then, the main control chip switches the operation mode from the low power consumption mode to the standard mode, when uplink data to be transmitted in the cache is transmitted, the iridium device firstly detects an iridium signal, and when the signal is good, the iridium device initiates a session and transmits the uplink data to the iridium. When the signal is poor or the continuous and multiple times of uplink data transmission to the iridium satellite fails, the iridium satellite device enters a sleep mode, and tries to transmit the uplink data to the iridium satellite again after waiting for being awakened next time.
The interrupt triggered by the IO module is the interrupt triggered by the iridium device, and the IO module is a module for processing emergency. When a user operates the iridium device through a key on the iridium device, the IO module responds to a key instruction for the iridium device and triggers IO interruption. And then, the main control chip switches the operation mode from the low power consumption mode to the standard mode, and automatically generates an emergency help-seeking message according to the information of the emergency contact person, the current GPS coordinate and the like prestored in the iridium device, and in the state, the iridium device ignores the situations of the iridium user number of washing and failure of sending, and continuously sends the emergency help-seeking message until the sending is successful or the user manually cancels the sending.
Three implementations of triggering interrupts are described in the embodiment of fig. 4, and the operation mode switching will be described below with reference to fig. 5. Fig. 5 is a schematic diagram of switching operation modes provided in the embodiment of the present application, as shown in fig. 5, including:
s51, RT _ Thread PM component initializes.
The RT _ Thread PM component is a component in an operating system of the iridium device, and is initialized after the iridium device is started.
And S52, polling all tasks.
After the RT _ Thread PM component is initialized, the iridium device can poll a task, and mainly judges whether uplink data to be transmitted or downlink data to be transmitted exist, detects data such as current coordinates, iridium device voltage, temperature and humidity and updates iridium device state information.
And S53, judging whether the system is idle, if so, executing S54, and if not, executing S52.
When the uplink data to be transmitted or the downlink data to be transmitted exist, the iridium satellite device is not in an idle state, and S52 is executed; and when the uplink data to be transmitted or the downlink data to be transmitted does not exist, the iridium satellite device is in an idle state, and S54 is executed.
S54, enter a low power mode.
When the iridium satellite device is in an idle state, the iridium satellite device defaults to enter a low power consumption mode so as to save power consumption.
And S55, triggering an interrupt and switching to the standard mode.
When the iridium satellite equipment is in a low power consumption mode, if an interrupt event occurs, an interrupt is triggered. The implementation manner of triggering the interrupt may be any one of the three implementation manners of the embodiment in fig. 4.
After the interrupt mode is triggered, the iridium equipment is switched to the standard mode, and each task runs normally. When the iridium device detects that the iridium signal is good, data transmission between the terminal device and the iridium can be performed.
Fig. 6 is a schematic diagram of data transmission provided in an embodiment of the present application, and as shown in fig. 6, an iridium device includes a sending buffer and a receiving buffer, where the sending buffer is used to store uplink data to be transmitted, and a second flash memory is used to store downlink data to be transmitted.
When the terminal equipment needs to send uplink data to the iridium satellite, the terminal equipment sends the uplink data to be transmitted to the iridium satellite equipment, the iridium satellite equipment receives the uplink data to be transmitted through the Bluetooth module, and then the uplink data are stored in the sending cache.
The iridium device judges whether downlink data exist according to response information fed back by the iridium during conversation, when the iridium has the downlink data, the iridium device initiates the conversation to receive the downlink data, and the iridium device acquires the downlink data to be transmitted from the iridium through the transceiver module and stores the downlink data to the receiving cache.
Therefore, after the iridium satellite device is switched from the low power consumption mode to the standard mode, each task is normally operated. And when uplink data exist, the iridium equipment establishes a session to transmit the uplink data, otherwise, the iridium equipment still establishes a session so as to be convenient for the iridium equipment to judge whether the downlink data exist in the iridium according to the response information of the iridium. When the iridium satellite has downlink data, the iridium satellite equipment establishes a session, receives the downlink data of the iridium satellite, and then stores the downlink data in a receiving cache. And when the terminal equipment is connected with the iridium equipment, the iridium equipment sends the downlink data in the receiving cache to the terminal equipment.
S56, exiting the low power mode and executing S52.
And after the data transmission task between the terminal equipment and the iridium satellite is executed, the iridium satellite equipment exits the low power consumption mode when the iridium satellite equipment is recovered to be idle so as to save power consumption.
The process will be described with reference to the specific figures.

And after the iridium device is powered on and initialized, creating each subtask. The Bluetooth module is responsible for writing the received uplink data into the sending cache, and waits for the iridium transceiving thread to read and send the uplink data in the sending cache. The Bluetooth module is connected to the LPUART interface of the main control chip, and only the LPUART can normally work when the main control chip is in a low power consumption mode.

Fig. 9 is a schematic flow chart of data transceiving of a transceiver module according to an embodiment of the present application, as shown in fig. 9, including:
s91, judging whether the sending buffer is empty, if not, executing S92, and if yes, executing S93.
The iridium device firstly judges whether uplink data to be transmitted exist in a sending cache.
And S92, sending the uplink data in the sending buffer to the Iridium.
And if the uplink data exist in the sending buffer, reading the uplink data and sending the uplink data to the Iridium satellite. Because the iridium device can trigger the interrupt through the scheme of the timer and switch the operation mode to the standard mode, when the iridium device is awakened by the timer, the iridium device needs to establish connection with the iridium for judging and receiving downlink data sent by the iridium even if the sending cache does not contain the uplink data.
S93, determine whether the downlink data is greater than or equal to 1, if yes, go to S94, and if no, go to S95.
After the iridium device and the iridium are connected, a transceiver module in the iridium device can receive downlink data and can acquire the state of the iridium, including the quantity of the downlink data to be transmitted.
And S94, acquiring the downlink data.
And when the quantity of the downlink data to be transmitted is greater than or equal to 1, repeating the operation, receiving the downlink data from the iridium satellite until the downlink data of the iridium satellite is completely received, writing the received downlink data into a receiving cache, and then waiting for the Bluetooth module to read the downlink data in the receiving cache for transmission.
And S95, sending the downlink data to the terminal equipment.
S96, delay, yield scheduler.
The scheduler may be released when no downstream data needs to be transmitted.
In the examples of fig. 7 to 9, the iridium device may switch the operation mode through several interrupt modes, wake up the iridium device, and after the iridium device is woken up, execute the task from the last place where the iridium device enters the low power consumption mode. In the implementation mode of timer interruption, after the timer reaches a timing period, the flag bit of the timer is reset while the iridium device is awakened, so that the iridium thread establishes connection with the iridium at least once, and is used for judging whether downlink data transmission exists or not and carrying out corresponding processing. In the implementation mode of interruption triggered by the LPUART module, after receiving uplink data sent by the terminal equipment, the Bluetooth module triggers the LPUART module to receive interruption, and the interruption wakes up the iridium device and resets the Bluetooth idle zone bit at the same time. In IO interruption triggered by the IO module, level jump of a Bluetooth state pin triggers the IO interruption, and the Bluetooth idle zone bit is reset while the Iridium equipment is awakened by the IO interruption.
According to the iridium device control method, device and system provided by the embodiment of the application, the operation mode of the iridium device is switched from the low power consumption mode to the standard mode by the iridium device according to the interrupt event in the low power consumption mode, the session is established with the iridium device in the standard mode, and the bluetooth connection is also established between the iridium device and the terminal device, so that when the iridium device detects that the iridium signal is good, the iridium device can be used as a relay to perform data transmission between the terminal device and the iridium device, and the data transmission can comprise uplink data transmission and downlink data transmission. According to the scheme of the embodiment of the application, when data transmission is not needed, the iridium device is in the low power consumption mode so as to reduce standby power consumption, when data transmission is needed, the operation mode is switched according to the interruption event, data transmission between the terminal device and the iridium device is completed after the operation mode is switched, reasonable switching of the operation mode of the iridium device can be achieved, and normal communication between the terminal device and the iridium device is guaranteed under the condition that the standby power consumption of the iridium device is low.
